It flutters a little at WOT other then that runs great. Not for sure if i should go up or down a main.

It has the Ctracing kit and running on 110 octane full mixed 40:1

Raise the needle a notch.
Why 110?
Maybe try going to 32:1
:)

Thats what the engine builder recommended. I raised the clip and all is good. Im just concerned about overheating now...how will i know a aircooled engine is getting hot?
